Cell phone battery life has always been the part of the purchase of the machine is more concerned about, after all, any of your performance and then excellent, value and then heavenly, the image is again outstanding, if the battery life does not work, the user will not accept the same.
In reality, the factors affecting the duration of the cell phone are indeed quite a few. Cell phones are electronic aggregates, a complete cell phone is composed of hundreds of thousands of electronic components, as long as these components are in operation, power consumption is inevitable.
Want to extend the life, manufacturers can do nothing more than use lower power consumption configuration, or increase the battery capacity of the phone. And, with the development of cell phone fast charging technology, high-power fast charging to some extent is also regarded as an important means to extend the life of the phone.
For consumers, we buy a machine, naturally hope that the bigger the better the battery, fast charging the faster the better, so with a large battery and high-power fast charging models will always be more attractive. But see here, I believe that many friends also have questions, what is the correlation with the battery single and dual-core design? In fact, there is still a great relationship.
And the past design is different, today's cell phone battery is completely closed in the case, non-professionals are not recommended to dismantle at will, and even if you want to take apart to see, there is no appropriate tool is also very difficult to do, so very few users really care about the battery in fact is a single-cell or dual-cell.
In fact, cell phone batteries do differ between single and dual batteries, that is, one battery and two batteries. Why there is such a difference is actually related to fast charging.
Early smartphones have basically been single-cell batteries, due to the development of earlier, the technology has been very mature, in addition, because the fast charging technology has not been widely used, which means that the battery in the charging, the voltage and current are maintained at a lower level, for the battery life of the impact of the natural low, so there are some advantages in the battery life, the number of times of charging and discharging.
With the development of fast charging technology, fast charging power also continues to refresh the industry upper limit, 60W +, 80W and then 100W +, the fast charging industry rolled to the fly, accompanied by the popularity of cell phone charging technology, charge pump + dual-cell program is also rapidly popular.
Dual cell program does have significant advantages, in the case of battery technology is difficult to get a breakthrough, dual cell from the physical level to solve the problem of higher charging power. But in today's cell phone market, dual cell is still the mainstream. As mentioned earlier, the reason why the dual cell has a higher charging efficiency, because of the use of dual charging, in addition to lithium batteries to withstand the limitations of the current and single voltage, dual-cell design and cleverly avoid these limitations, so it is suitable for high-power fast charging.
Generally speaking, an ordinary lithium battery contains a positive and a negative two lugs, while the double lugs single cell technology, to do in a cell put down two positive and one negative, three lugs, so that in the battery on the internal formation of two circuits, which can be leveled out of high-power fast-charging current and voltage, and in the enhancement of charging power at the same time, to ensure that the battery is always in a safe charging range.
It is based on such a battery design scheme, some of the drawbacks of the single-cell has been solved, you can use a higher-power fast charging, to achieve charging efficiency comparable to the dual-cell, while the battery heat is smaller, the battery life has also been improved. Of course, the greater dividend also lies in saving more space in the body, dual-cell series connection can be doubled to pull up the total input voltage, but the same battery capacity accounted for the volume is also larger, the thickness of the phone will inevitably increase in the case of cell phone body inches, single-cell design is more in line with the manufacturers to create a thin and light product concept.
Single-cell and dual-cell cell phone batteries, both programs have distinct advantages, but do not really overwhelm each other.
In charging efficiency, dual-cell is really better; and in the thickness of the phone, theoretically the same capacity single-cell batteries are thinner than dual-cell.
In the actual experience it is difficult to say who has an advantage over who.
